SAFETY INFORMATION
EVU00070
This off-highway utility vehicle handles differently from other vehicles including cars and ATVs.
SEVERE INJURY OR DEATH can result if you do not follow these instructions:
● Read this manual and all labels carefully and follow the operating procedures described.
● This vehicle is designed to carry the driver and one passenger. Never carry passengers in the
cargo bed.
● Always be sure the driver and passenger are wearing seat belts.
● Never give a ride to a passenger who is too small to reach and hold the handgrip on the enclo-
sure.
● Always avoid operating the vehicle on any paved surfaces, including sidewalks, driveways,
parking lots, and streets.
● Never operate this vehicle on any public street, road, or highway, even a dirt or gravel one.
● Never operate this vehicle without wearing an approved motorcycle helmet that fits properly.
You should also wear eye protection (goggles or a face shield), gloves, over-the-ankle boots,
long-sleeved shirt or jacket, and long pants.
● Never consume alcohol or drugs before or while operating this vehicle.

● Always inspect your vehicle each time you use it to be sure it is in safe operating condition. Al-
ways follow the inspection and maintenance procedures and schedules described in this manual.
● Always keep both hands, arms, feet, and legs inside the vehicle at all times during operation.
Keep your feet on the floorboard. Never hold onto the enclosure except when using the handgrip inside the enclosure. Otherwise, your hand could be injured if it is caught between the enclosure and an obstacle outside the vehicle.
● Always keep both hands on the steering wheel when driving.
● Never wrap your thumbs and fingers around the steering wheel. This is particularly important
when driving in rough terrain. The front wheels will move right and left as they respond to the
terrain, and this movement will be felt in the steering wheel. A sudden jolt could wrench the
steering wheel around, and your thumbs or fingers could be injured if they are in the way of the
steering wheel spokes.
● Always go slowly and be extra careful when operating on unfamiliar terrain. Always be alert to
changing terrain conditions when driving the vehicle.
● Never operate on excessively rough, slippery, or loose terrain until you have learned and prac-
ticed the skills necessary to control the vehicle on such terrain. Always be especially cautious
on these kinds of terrain.
EE.book Page 2 Wednesday, August 2, 2006 5:10 PM
●
Never operate on hills that are slippery or ones where you will not be able to see far enough
ahead of you. Never go over the top of a hill at speed if you cannot see what is on the other
side.
● Always follow proper procedures for going uphill. If you lose momentum and cannot continue
up a hill, back down the hill with the engine in reverse gear. Use engine braking to help you go
slowly. If necessary, use the brakes gradually to help you go slowly.
● Always check terrain carefully before going down hills. Go as slowly as possible. Never go
down a hill at high speed.
● Always check for obstacles before operating in a new area.
● Never operate the vehicle in fast flowing water or water deeper than the floorboards on this
model. Remember that wet brakes may have reduced stopping ability. Test your brakes after
leaving water. If necessary, apply them several times to let friction dry out the linings.
● Always be sure there are no obstacles or people behind you when you operate in reverse.
When it is safe to proceed in reverse, go slowly. Do not brake abruptly when carrying loads in
the cargo bed.
● Always use the size and type of tires specified in this manual.
● Always maintain proper tire pressure as described in this manual.
● Never exceed the stated load capacity. Cargo should be as far forward in the bed as possible,
